Chapter 2: Installation

Installing the Speed Transducer (Through Hull)

For accurate speed readings, locate the speed transducer in the
shaded 'clear flow' areas as shown.
The transducer should also be:
• Ahead of propellers (10% W.L. length minimum)
• At least 6in (150mm) from the keel (with sailing yachts siting should
be forward of the keel)
• Near the centreline of the vessel
• Clear of other through hull fittings or projections
• Have sufficient clearance inside the hull to allow the nut to be fitted
• Have 4in (100mm) clearance above the through hull fitting for
withdrawal
Note: The speed transducer cable can, if required, be shortened.
However, new 1/8in lug connectors must be crimped to the shortened
cable.
